SPECIFICATION forming part of Letters Patent No. 640,337, dated January2, 1900.

Application filed October 5, 1899.

To (all whom, it may concern:

Be it known that I, Auo osrns TORREY, a citizen of the United States ofAmerica, residing at Detroit, in the county of lVayne and State ofMichigan, have invented certain new and useful improvements inDumping-Oars, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention refers more particularly to self-dumping cars principallydesigned for carrying dirt or gravel along the road-bed; and the objectof the invention is to adapt the car either to dump its full load,one-half on each side of the track, or to dump one-half of its load onlyat a time and to dump it each time alike and close to the track, and,further, to divide equally loads of various amounts and character.

While in the present state of the art it is not new to make adumping-car which permits the fractional discharge of a load, so thatthe material can be distributed along the roadbed, it is not dumped atthe same distance from the rail every time-that is to say, the car-bodyis made with two tiers of dischargedoors in the sides, the top onesbeing first opened to dump one part of the load and then the rest isdumped by opening the lower tier.

On account of the upper tier being so much higher up the materialinstead of being dumped close to the ends of the ties, as from the lowerdischarge-doors, is thrown considerably outward and requires extra workin shoveling, and often the road-bed is not wide enough to permit ofdumping at all from the upper discharge-doors. Furthermore, there is nocertainty of the load being equally divided, and any excess over thenormal load for which the car is built is dumped with the firstdischarge, while if the load is below the normal the first dumping wouldbe smaller than the second. It is further apparent that the character ofthe material to be dumped will affect uniformity of (lumping.

This invention entirely remedies these objections; and to this end itconsists in a new construction in which the car-body is divided by twoinside partitions longitudinally of the car into a central pocket andtwo outside pockets, the central pocket having means for discharging tothe outside pockets and the Serial No. 732,605. (No model.)

latter having low-down discharge-doors to the outside, so that afterdumping the contents of the outside pockets the second half of the loadis supplied from the central pocket, which opens into both outsidepockets, and from there through the same discharge-doors through whichthe first dumping was made to the ground, thus making two dumpings inprecisely the same relative place at the ends of the ties where it ismost convenient for use. Furthermore, by a peculiar arrangement of thedividing-partitions the load is always equally divided in the loading ofthe car, all as more fully hereinafter described, and shown in theaccompanying drawings, in which- Figure l is a vertical centralcross-section of a dumping-car embodying the invention. Fig. 2 is adiagram side elevation thereof, and Fig. 3 is a plan of the duplexWindlass for controlling the opening and closing of the discharge-doors;

In the drawings the invention is shown as applied to the car-body of thewell-known type of self-dumping side-discharge gravelcar, in which A isthe bed-frame; B and B, the end and side walls, respectively; O C,transverse division-walls in the center, dividing the car-body betweenthe ends into two compartments for the load; D, the dischargedoors inthe sides, and E the chute-boards, forming the bottom of thecompartments, all arranged and operating in the known manner, except asmore fully hereinafter described.

Each compartment is divided interiorly by longitudinal partition-wallsinto a central pocket I and two outside pockets J, and the lower portionof each partition-wall constitutes a discharge-door M, opening outwardlyfrom the pocket I into the outside pocket J, adjacent thereto.

To support the interior partition walls, cross-beams K are secured atintervals upon the side walls, and to these the longitudinal beams L aresupported, to which the discharge-doors M are hinged. Above the beams Lthere are secured to the cross-beams K the vertical guides N, adapted toremovably hold in position one or more top boards 0, according to theheight to which the car is to be loaded.

The discharge-doors D and M are respec tively connected to winding-drumsP and Q, suitably journaled in the center of the carbody in the spacebelow the floor, and these winding-drums are in turn operated by meansof a duplex Windlass R, mounted on top of the car. This Windlass issupported upon a suitable gallows-frame aabove the central transversepartitions O C to one side of the longitudinal center, and comprises thewinding-shafts b c, journaled in parallel relation to each other, eachhaving a hand-wheel d, secured to opposite ends of the shafts andconnected by chains or cables with the drums P and Q, respectively,whereby one shaft controls the opening and closing of the doors D andthe other the opening and closing of the doors M.

Each of the shafts c and b carries a grooved friction pulley 6, providedwith frictionblocks f, fitting the face of the pulleys and adapted to bepressed thereto by means of screws operated by the hand-wheels g, all soarranged that if the friction-blocks are screwed tightly upon thepulleys the shafts b and c are prevented from revolving, and therebyprevent the unwinding of the chains or cables which hold the doors M andD closed.

The chains or cables kit, which connect the Windlass with the drums Pand Q, pass down in the opening or well formed between the partitions CO, and to prevent in loading the dirt from falling into this well asuitable saddle S is placed over it. Saddles T are also placed over theopenings U, through which the connections of the doors M pass throughthe floor.

In practice the parts being constructed as shown and described they areintended to operate as follows: If the car is loaded along itslongitudinal center, it will be seen that after the central pocket I isfilled to the height of the longitudinal beams L or to the height of oneor more of the partition-boards O the dirt overflows into the outsidepockets and fills the same too, and the loading is completed when theload-lines in the inside and outside pockets coincide, and the threedotted lines in Fig. 1 indicate the load-lines at three differentheights of the longitudinal parti tions representing different cubicalcontents.- At each load-line an accurate division is made of theload-that is, the inside pocket contains one half of the cubicalcontents and the two outside pockets together the other half.

The entire load can be dumped by first releasing the hand-wheel g whichcontrols the inner doors M and afterward releasing the hand-wheel gwhich controls the outer doors D D or each half can be dumped separatelyby opening first the outside doors D and then after shifting the caropening the inside doors M also. The dirt from the inside pocket by thesimultaneous opening of the doors M, which have previously beenreleased, is divided, one-half passing out through each opening andthence through the openings in the outside pockets to the ground, thusmaking exactly the same division and depositing "the dirt in the samerelative place as at the first dumping.

The construction of the car may be variously modified within the spiritof the invention, which has for its principal object to dump one-half ofthe load in the same relative position to the track as the otherone-half is dumped and to deliver the material from the car thusirrespective of the amount or character of the material. Thus where thecar is designed to carry a minimum load only there is no need of theremovable divisionboards 0. In fact, the interior partitions may besolely represented by the doors M, and in this view the beam L is merelyfor convenience in hinging. It is also for the sake of convenience onlythat the car is divided transversely into two principal compartments,and it is obvious that the car-body may have but one principalcompartment, the operating devices being placed at the end of thecar-body instead of being in the middle, or the number of principalcompartments may be increased.

By placing the Windlass for operating the doors on top easy access isgained.to it by means of a suitable platform U, guarded by a railing V,While at the same time no valuable space is sacrificed, and it isobvious also that the open space in the middle of the car may bedispensed with, except as to leave sufficient space for the chains h72/.

Those acquainted with the use of dumpingcars in the construction andmaintenance of the road-bed of railways will readily understand thepractical value of the advantages of the invention.
